It makes sense that Peter Parker is unfamiliar with Gwen Stacy. He doesn’t know such a person at all.

And Gwen, the female spider, lives in Marvel Comics Earth 65, which is a brand-new universe, and in that universe Gwen Stacy became Spider-Man.
In Earth 65, Peter Parker is her childhood friend, and they are ambiguous, which is similar in Spider-Man.
Gwen lost herself after being bitten by a spider and turned into Spider-Man, and lived a decadent and confused life. In the process, Peter Parker was in danger because of Gwen.
Spider-Man Gwen failed to save Peter Parker. Peter died in an accident. Before Peter died, he tried to encourage Gwen-the greater the ability, the greater the responsibility. Now that you have superhuman ability, you should bear superhuman responsibility.
Peter Parker’s last words successfully inspired Gwen to make her prodigal girl return. Since then, Spider-Man Gwen has become a superhero to protect new york citizens and a good neighbor.
That’s why Gwen was shocked and shouted "You’re still alive" after seeing Peter Parker.
It’s a pity that Peter Parker will not understand all this for a while.
"Wait … let’s stroke us … you said you met me and we were childhood friends, and then you said I died in an accident. I told you before I died-the greater the ability, the greater the responsibility?" Peter asked frowning.
"Of course! Of course! " Gwen nods "don’t you forget? Oh, Shi I knew that the accident didn’t kill you, but it broke your brain … By the way, Peter, you turned into Spider-Man? You were bitten by a spider, too? "
"What do you mean I was bitten by a spider? Yes, I was bitten by a spider, okay? " Peter Parker is a little angry. He has always been, he is the only Spider-Man.
Then another super patrol police car came, and Steve Rogers and Bucky Barnes came from the car.
"What happened? Goofy seems to be a mess in Brooklyn. "
Steve has completely finished the great cause of losing weight, and the once strong American hip has returned to the rivers and lakes.
Goofy shrugged. "It’s true. Brooklyn is an unimaginable mess."
Steve looked back at the two guys who were both wearing Spider-Man tights and asked curiously, "Hey? What’s the situation? Is there a Spider-Man imitation contest here tonight? "
"Imitation?" Peter Parker was angry. "I’m not imitating. I’m Spider-Man!" "
Gwen also deeply dissatisfied "what should I imitate Spider-Man? I am Spider-Man myself! "
"I don’t understand this …" Steve looked at him with a broken face. Both of them called themselves Spider-Man Spider-Man. "Since when is Brooklyn full of Spider-Man?"
Peter Parker and Gwen didn’t like Steve’s statement very much, but after they looked at each other, they both realized that Steve was right
Then goofy came over and explained, "I think this is the case …"
Unexpectedly, he didn’t explain that Gwen saw Steve carrying a shield behind his back.
"Wait, this is not the US team shield? Why do you carry the US team shield? "
Steve simply said, "Because I am the American team. I am Steve Rogers. I think you have heard of this name?"
Gwen thought for a moment and then nodded. "Of course, I have heard of Steve Rogers’ roaring commandos who died in the battlefield during World War II. This is our primary school class …"
"What? !” Steve’s face turned black. "I died in the battlefield?"
"Yes!" Gwen nodded. "Wait … you should have the same name as Steve Rogers, right? After all, he died as early as World War II … "
Steve was messy and forced to remain calm on the spot and asked, "Then why do you question my identity as an American team?"
"Because the American team is Samantha Wilson! This is a well-known thing, "Gwen said naturally.
"Samantha … what?" Steve was completely confused.
Bucky Barnes is a blank face.
"Samantha Wilson, an outstanding black heroine in World War II, injected with super soldier serum and became the most powerful soldier in America, that is, captain America …" Gwen said as if she recited the text. "Come on, what is it like you heard this story for the first time?"
However, Gwen Spider didn’t expect that she was right this time-it was the first time for everyone except her to hear about it, and it was the first time to hear what Captain America was.
